摘要
DSP具有强大的事件管理能力,CPLD具有高速的逻辑运算能力。单个DSP配以CPLD可以产生多路PWM波,完成对四舵机的伺服控制。软件上,DSP完成AD采集、PID运算以及中断管理,CPLD完成多路PWM的产生以及实时保护的功能。该控制方式充分利用了DSP和CPLD的优点,既节约了成本,减小了体积,也提高了系统的可靠性。
DSP has powerful event management capabilities, and CPLD has high-speed logic operation capabilities. Single DSP together with the CPLD, can generate multiple PWM wave, to control four electrical actuators. DSP completed AD acquisition, PID operation and interrupt management, and CPLD completed muhi-channel PWM generation and real- time protection function. This control method takes full advantage of the advantages of DSP and CPLD, which not only saves the cost, reduces the system size, but also improves the reliability of the system.
